Lien is scheduled to meet with Hu during the trip, the first meeting between top leaders of the two parties in 60 years.

The last one took place in August 1945, when CPC Chairman Mao Zedong and KMT Chairman Chiang Kai-Shek met in Chongqing, a major city in southwest China, to negotiate an end to the civil war.

Nanjing, the first leg of Lien's visit, was once the capital of the KMT regime. Xi'an is the birthplace of Lien.

When the KMT described Lien's visit a "journey of peace," Lien said in Taiwan on Monday that "cross-Straits exchanges should no longer be hampered by the mindset of civil war." He expressed the hope that his visit could lay the groundwork for improved relations and closer trade links across the Taiwan Straits.
